Which of the following is a characteristic feature of an alcohol functional group?
A
Contains a carbonyl group
B
Contains a sulfhydryl group
C
Contains a hydroxyl group
D
Contains an amino group
Verified step by step guidance1
Identify the functional groups mentioned in the problem: carbonyl, sulfhydryl, hydroxyl, and amino groups.
Understand the structure of each functional group: A carbonyl group contains a carbon atom double-bonded to an oxygen atom (\(\)). A sulfhydryl group contains a sulfur atom bonded to a hydrogen atom (\(\)). A hydroxyl group contains an oxygen atom bonded to a hydrogen atom (\(\)). An amino group contains a nitrogen atom bonded to hydrogen atoms (\(\)).
Recall that alcohols are organic compounds characterized by the presence of a hydroxyl group (\(\)) attached to a saturated carbon atom.
Compare the functional groups listed in the problem with the characteristic feature of alcohols. Alcohols do not contain carbonyl, sulfhydryl, or amino groups as their defining feature.
Conclude that the characteristic feature of an alcohol functional group is the presence of a hydroxyl group (\(\)).
